Turkey-Israel Tensions Escalate, Testing US Policy and NATO’s Limits

Turkey has begun seeking Interpol Red Notices for Israeli Prime Minister Benjamin Netanyahu and an Israeli soldier, escalating a criminal case over Israel’s September 2025 interception of a Gaza-bound aid flotilla.

Ankara announced the move Aug. 21, three days after Israel bombed a Syrian air base that it said was about to receive Turkish forces. The legal case and the airstrike are separate, but both are intensifying the dispute between Israel and a NATO member.

Washington has stepped in to contain the military dispute. On Aug. 23, Syrian and Israeli delegations met in Jordan under U.S. mediation to discuss stopping further attacks and restarting negotiations on a security agreement.

The talks followed U.S. warnings that the Syrian air-base strike could have caused an unintended confrontation between Israeli and Turkish forces.

How Turkey Reached the Interpol Stage

The Global Sumud Flotilla included about 50 vessels and more than 500 activists attempting to deliver aid to Gaza and break Israel’s naval blockade.

Israeli forces stopped the flotilla in international waters in October 2025, detained those aboard and took them to Israel. Turkey opened an investigation Oct. 2 after Turkish citizens were detained. Israel maintains that the blockade and its interception of Gaza-bound vessels were lawful security measures.

Turkish prosecutors indicted Netanyahu and 34 other defendants in April 2026. They allege Israeli forces unlawfully stopped the vessels, detained and assaulted activists, damaged property and seized aid.

The charges include genocide, crimes against humanity, torture, intentional injury, unlawful detention and aggravated robbery. The defendants are being tried in their absence and have not yet been convicted.

On July 14, the Istanbul 11th High Criminal Court issued arrest warrants for Netanyahu and Afek Moskovitch—two of the 35 defendants.

Turkish prosecutors identify Moskovitch as an Israeli lieutenant in the 71st Armored Battalion and separately accuse him of posting video showing tanks and a bulldozer destroying the Turkish-Palestinian Friendship Hospital and an adjoining medical school in Gaza.

Public Turkish filings do not clearly explain why he was one of only two defendants selected for an Interpol request or what his role was, if any, regarding the flotilla.

Turkey’s Justice Ministry announced Aug. 21 that it had asked the Interior Ministry to seek Red Notices for both men and had sent the documents to the Foreign Ministry.

That announcement began the application process; it does not mean Interpol has approved or circulated the notices.

Netanyahu’s office rejected the case as a “pathetic attempt” by Turkish President Recep Tayyip Erdogan to intimidate Israeli leaders and military personnel.

What a Red Notice Would Do

If Interpol approves the requests, the notices would ask police worldwide to locate Netanyahu and Moskovitch and consider provisional arrest while Turkey pursues extradition or another legal process.

A Red Notice is not an international arrest warrant, and Interpol cannot order another country to arrest anyone. Each country decides what effect to give the notice under its own law.

Interpol must determine whether Turkey’s requests comply with Article 3 of its constitution. The provision bars Interpol from intervening in matters that are predominantly political, military, religious or racial, making it relevant when a government seeks notices against another country’s political and military figures.

Most approved Red Notices remain restricted to law enforcement, so a missing public listing does not prove that no notice exists.

The United States treats a foreign Red Notice as a lookout request (BOLO). It cannot arrest someone on the notice alone because that would not satisfy the Fourth Amendment.

Turkey would need to use applicable extradition procedures and provide information sufficient for an American court to issue a warrant. Netanyahu’s separate 2024 International Criminal Court warrant involves different allegations and is unrelated to Türkiye’s current request.

Why the Syria Strike Raised the Stakes

Israel carried out eight strikes against the Abu Duhur air base in northwestern Syria on Aug. 18, damaging its runway but causing no reported casualties. Israel said it was preventing a Turkish deployment.

Syrian officials denied any deployment plan but confirmed that Turkish personnel had visited the base one day earlier to inspect rehabilitation work. The attack therefore placed Israeli military operations at a facility where personnel from a NATO country had recently been present.

U.S. envoy Tom Barrack said Israel warned neither Washington nor Ankara beforehand. He said Turkish forces could have scrambled aircraft after detecting Israeli jets approaching the border without knowing their destination, creating the possibility of a direct Israeli-Turkish confrontation.

Israeli Defense Minister Israel Katz disputed Barrack’s account and said Israel had provided intelligence simultaneously to U.S. and Syrian officials.

The Aug. 23 talks also addressed the danger reflected in Barrack’s warning: preventing Israel-Türkiye tensions from spilling onto Syrian territory.

What NATO Could Do

The Aug. 18 strike did not trigger NATO’s Article 5 because it hit a Syrian base and no Turkish forces were reported harmed.

Article 5 is the alliance’s collective defense clause, which treats an armed attack against one member as an attack against all. Even when Article 5 applies, it does not automatically send the United States to war; each ally chooses the assistance it considers necessary.

Article 6 defines Article 5’s geographic reach, covering Turkish territory and allied forces, ships and aircraft in member territory, the Mediterranean and specified North Atlantic areas. NATO describes those provisions as geographic limitations, and Syria is not included.

Turkey could counter that Article 6 says covered attacks are “deemed to include” the listed situations without expressly saying the list is exclusive. Ankara could therefore argue that a deliberate strike on its armed forces constituted an attack against Turkey itself.

That argument would rest on the nationality and official status of the personnel, not sovereignty over the base. Foreign military installations ordinarily remain territory of the host country, so a Turkish presence at Abu Duhur would not make the Syrian base Turkish territory or independently place it within Article 6’s geographic coverage.

NATO decides case by case whether an incident qualifies as an armed attack. Turkey’s argument would still face two obstacles: Article 6 does not include Syrian territory, and NATO has previously treated attacks on Turkish personnel there as security threats warranting consultations rather than Article 5 collective defense.

NATO faced a similar situation in February 2020, when airstrikes killed Turkish soldiers in Syria’s Idlib province. Turkey invoked Article 4, not Article 5. Article 4 allows any ally to call consultations when it believes its territory, political independence or security is threatened. No armed attack is required.

NATO condemned the strikes, expressed solidarity with Turkey and continued supporting its air defenses, but it did not activate collective defense.

Turkey also used Article 4 in 2012 after Syria shot down a Turkish military aircraft and Syrian shells killed five civilians inside Turkey. NATO allies later deployed six Patriot missile batteries there under NATO command and control to defend against possible missile attacks from Syria.

Those cases show that Article 4 can produce practical military support even when the alliance does not invoke Article 5. Article 4 therefore remains Turkey’s more plausible route if tensions with Israel escalate in Syria.

Another strike involving Turkish personnel could bring the dispute before NATO without settling the Article 5 question, leaving Washington to manage a confrontation between a close security partner and a treaty ally.

Washington’s Fighter-Jet Dilemma

The dispute comes as Washington weighs how much advanced airpower to provide Turkey. In 2024, the State Department approved a possible $23 billion package for new F-16s and upgrades to existing aircraft and weapons.

The F-35 question remains more contentious. President Donald Trump said July 7 that a sale was “something we will consider” and announced plans to remove sanctions imposed over Turkey purchase of Russia’s S-400 air-defense system. The State Department later told Congress that U.S. law still prohibits an F-35 transfer until Turkey relinquishes the S-400 and satisfies other statutory conditions.

Netanyahu has urged Washington not to provide Turkey with F-35s or their engines, arguing that the aircraft would threaten Israel’s regional air superiority. His objection also carries legal relevance because U.S. arms-sale law requires the administration to evaluate whether sales to other Middle Eastern countries would harm Israel’s “qualitative military edge.”

Israel also has limited industrial leverage: Israel Aerospace Industries manufactures F-35 wing structures, while a Collins-Elbit joint venture supplies the jet’s helmet display. An Israeli official reportedly threatened to withhold Israeli-produced technology from F-35s sold to Turkey.

Further escalation would leave Washington managing a crisis between a NATO ally and one of its closest security partners while considering a fighter sale that Israel says would erode its regional air advantage.

Washington must now contain the risk of a military clash between NATO ally Turkey and close security partner Israel while deciding whether to sell Ankara advanced aircraft that Israel argues would shift the region’s balance of power.
